In testing on our bows we have found the SBD Ultra string up to a 6.3 fps gain with a 30" draw on light weight limbs and a 2.8 fps gain at a 28" draw. Heavier limbs will show less of a performance gain. These strings should not be used on bows above 53lbs.

Silent But Deadly Bow Strings are hand made Flemish twist bow strings and not just another bow string, it’s a string crafted for traditional bow hunters. 

Silent But Deadly Bow Strings are the "Original Skinny String" crafted for the traditional bow hunter. 

Our goal in string making is to achieve the quietest string with the least amount of stretch and the best performance for hunting that we could craft. We have found through months of chronographing and testing different bows and strings combinations that our 6 strand D-10 with B-50 taper padded loops, for most bows, achieved the best results in reaching our goal. Our 2 bundle strings (skinny strings) employ a technique learned from a master string maker which form a perfectly round string that helps dampen string noise and vibrations.
